![Stratigraphic columns of Pocaterra Creek Member (PCM) of the Cadomin Formation. Column on the left is of the PCM type section on Pocaterra Ridge (modified from Ricketts and Sweet 1986, fig. 19). The palynomorph assemblage analyzed by Ricketts and Sweet (1986) was collected approximately 41 m above the base of the PCM. Column on the right is the section we measured on Grizzly/Highwood Ridges, where the vertebrate fossil specimens UALVP 59792–UALVP 59794 were found. The “needle” siltstone is characteristic of the upper third of the Elk Formation (Ricketts and Sweet 1986). Sediment grain size abbreviations: c, clay; p, pebble; s, sand; and z, silt.]()
